A typical Concord NH roof replacement runs $5,900 to $10,900 in 2026 (VHCI v2.0) — the most affordable metro in New Hampshire — modeled from federal wage and price data plus a snow-and-ice climate modifier. The local twist: the capital's Historic District Commission can require natural slate or copper in the State House district.
As of 2026, replacing a standard 22-square (about 2,200 sq ft) residential roof in Concord, New Hampshire costs between $5,900 and $10,900, with a mid-point of $8,000 (VHCI v2.0) — the most affordable of New Hampshire's metros. Those figures come from the Vanderflip Home Cost Index, which builds every number from the U.S. Bureau of Labor Statistics mean roofer wage of $22.65/hour for the Central New Hampshire nonmetro area (SOC 47-2181, BLS area 3300002), a U.S. Bureau of Economic Analysis Regional Price Parity of 104.165, and a 1.22 climate modifier for New Hampshire snow load, mandatory ice-dam protection, and steep-pitch waste, with a $600 tear-off allowance. No proprietary contractor databases are used.

Concord is New Hampshire's capital and its most affordable roofing metro, and the Vanderflip Home Cost Index puts a standard 22-square replacement at $5,900 low, $8,000 mid, and $10,900 high (VHCI v2.0). The number is low for the state because Concord sits in a Central New Hampshire nonmetro labor area, away from the Boston-influenced wage pressure of the southern border — but it is still a cold-climate roof carrying snow-load framing, a mandatory ice-dam membrane, and, in the historic core, a design-review overlay most cities never see.
The labor component is anchored to public data. The U.S. Bureau of Labor Statistics reports a mean roofer wage of $22.65/hour (SOC 47-2181) for the Central New Hampshire nonmetro area (BLS area 3300002) — the lowest of the VHCI New Hampshire metros. The index loads that base wage for burden and overhead, then scales the material rate by the U.S. Bureau of Economic Analysis Regional Price Parity of 104.165, and applies a 1.22 snow-and-ice climate modifier for the ground snow load, the code-required ice-and-water barrier, and the 12–15% waste that steep capital-core pitches add. A $600 tear-off allowance covers stripping the old roof to the deck. Together these produce the low, mid, and high bands above (VHCI v2.0).
Two things move a Concord number more than anything else: whether your home sits in a historic district (which can force natural slate or copper), and how steep and cut-up your roof is. The sections below walk through the permit, the Historic District Commission, the statewide HIC registration, the 2024 IRC and its mandatory ice barrier, the snow load, the ice-dam threat, the capital's institutional labor market, and the Merrimack flood zone, in the order they hit your wallet.
The City of Concord does require a building permit for a re-roof, and the fee is valuation-based: about $121.20 on a typical roof — a $30 base fee plus $7.60 per $1,000 of project valuation. Apply online through the CSS Citizen Self Service Portal, or in person at Code Administration, 37 Green Street, Concord NH 03301, (603) 225-8580, [email protected].
The roofing contractor typically pulls the permit. Unpermitted roofing work can surface at resale and complicate an insurance claim, so confirm in writing that your contractor is filing through the CSS portal before the job starts. If your home is in a historic district, the permit is only half the paperwork — see the next section.
Concord is the seat of New Hampshire state government, and the State House historic district and surrounding capital core fall under the Concord Historic District Commission (HDC). Inside these districts a re-roof is not just a permit — it requires a Certificate of Appropriateness (COA) reviewing the roof's material, color, and profile before any work begins.
The consequence is material. On a contributing historic structure, the Commission can require natural slate or copper rather than asphalt shingle to preserve the streetscape, which moves the project well above the asphalt VHCI band. If you own in or near the State House district, confirm your HDC status and secure the COA before you order materials — a slate roof specified after an asphalt bid is a very different number.
New Hampshire does not license roofers and has no roofing trade exam. Under RSA 310-A:188 through 310-A:198, home improvement contractors register with the Office of Professional Licensure and Certification (OPLC), carrying a minimum $25,000 general liability policy. Registration confirms a business exists and is insured to the statutory minimum — it is not a competency check, because there is no exam. Verifying skill, insurance, and in-state references is your job, and it matters more in Concord where a historic job may demand slate or copper craftsmanship. Confirm registration at oplc.nh.gov before signing.
Concord enforces the International Residential Code (IRC), and New Hampshire is mid-transition to the 2024 IRC: a concurrency window runs through December 31, 2026, after which the 2024 edition is mandatory statewide. If you re-roof in 2026, confirm which edition Code Administration is enforcing, because it changes underlayment and ventilation details.
One provision is not optional anywhere in New Hampshire: the ice barrier. Under IRC R905.1.2, a self-adhering polymer-modified bitumen membrane meeting ASTM D1970 is mandatory at the eaves, running from the edge up the roof to at least 24 inches inside the exterior wall line. Concord roofs are designed to a 110 MPH wind speed in Exposure Category B — the sheltered inland exposure — so the fastening schedule is lighter than the coastal Seacoast, but the ice-and-water barrier is identical statewide.
Snow load is the dominant structural driver in Concord, and it is the heaviest in the VHCI New Hampshire set. Concord carries a 70 PSF ground snow load from the U.S. Army Corps of Engineers ERDC/CRREL study TR-02-6, with an elevation-dependent range of 61.6 to 75.8 PSF across the city. Concord also sees 60.5 to 68.2 inches of annual snowfall. That combination drives heavier framing and makes drainage, flashing, and the eave ice barrier the difference between a roof that lasts and one that leaks — and it is a major reason steeper capital-core roofs favor snow-shedding standing seam metal or slate.
Ice dams are the number-one roofing failure mode in New Hampshire, and heavy-snow Concord is squarely exposed. The mechanism is freeze-thaw: heat escaping through the roof deck melts the underside of the snowpack, the meltwater runs to the cold eave and refreezes into a growing dam, and water backing up behind that dam is forced under the shingles and into the house. No shingle system sheds water uphill, which is why the code answer is a membrane, not a covering.
That is what the statewide ASTM D1970 ice-and-water barrier does under IRC R905.1.2: it seals the deck at the vulnerable eave so that even when a dam forms, the deck stays watertight. Proper attic insulation and ventilation reduce the heat loss that starts the cycle and should always be part of the job — but the membrane is the required last line of defense.
Concord's roofing labor market is steady rather than spiky, and that is why it prints the most affordable bands in the state. As the state capital, Concord's largest employers are institutional: NH State Government, the State Hospital, and Concord Hospital. Their construction and facilities work gives local crews a reliable base of demand without the wage surges that the Boston-adjacent border metros see, so the nonmetro $22.65/hour wage floor holds and Concord stays the value leader among the VHCI New Hampshire metros.
The practical effect for a homeowner: Concord bids tend to be tighter and less volatile than Nashua or Seacoast bids, but availability still narrows in the short northern building season and after a hard winter, when ice-dam repairs compete with planned re-roofs for the same crews.
Concord's housing stock splits by geography. The capital core and older neighborhoods around the State House carry steep 8:12 to 12:12 pitches, cut-up rooflines, dormers, and turrets that push cut waste to 12–15% and, in the historic districts, may require slate or copper under HDC review. The newer suburban edges of the city have simpler, moderately pitched roofs where waste runs closer to 10%. Two identical-square-footage homes can price meaningfully apart for pitch and district alone, which is why the estimator lets you slide roof size and why a steep, historic roof lands at the high end of your band.
The Merrimack River runs through Concord, and properties near it can fall inside FEMA Zone AE on the Flood Insurance Rate Map (check yours at msc.fema.gov). Zone AE carries a base flood elevation and triggers the 50% Substantial Improvement Rule, which can pull structural and elevation requirements into a large roofing or re-framing project on an older riverfront home. It rarely affects a simple shingle swap, but it is worth checking before a major structural job near the river.
Material choice in Concord is a cold-climate calculation shaped by heavy snow and, in the historic core, by the Historic District Commission. Within the code-required assembly — ASTM D1970 at the eaves — the four systems below are ranked by how they answer snow, ice, and Concord's design-review reality.

Architectural-asphalt VHCI v2.0 bands scaled from the 22-square baseline.
Concord carries the lowest VHCI wage floor in the state ($22.65/hr nonmetro), steady institutional demand from NH State Government and the hospitals rather than Boston-driven wage spikes, and no coastal wind premium (110 MPH, Exposure B). The offset is upward: a 70 PSF snow load — the highest in the VHCI New Hampshire set — and, in the historic core, a possible slate or copper requirement (VHCI v2.0).
The VHCI generates roofing cost estimates using U.S. Bureau of Labor Statistics Occupational Employment and Wage Statistics data (SOC 47-2181, Roofers, Central New Hampshire nonmetro area 3300002, $22.65/hr), U.S. Bureau of Economic Analysis Regional Price Parities (104.165), U.S. Army Corps ERDC/CRREL TR-02-6 snow loads, and a regional snow, wind, and building-code modifier (1.22) sourced from state and municipal government publications. No proprietary commercial construction database is used at any stage.
These figures are modeled estimates published for educational and informational purposes only — not quotes, appraisals, or construction advice.

VHCI v2.0 puts a typical Concord roof replacement at $5,900 low, $8,000 mid, and $10,900 high for a 22-square asphalt roof — the most affordable metro in New Hampshire. It is built from the BLS $22.65/hr nonmetro roofer wage (SOC 47-2181, Central NH area 3300002), a BEA Regional Price Parity of 104.165, and a 1.22 snow-and-ice modifier with a $600 tear-off allowance.
Yes. The City of Concord requires a building permit for a re-roof, costing about $121.20 — a $30 base fee plus $7.60 per $1,000 of project valuation. Apply online through the CSS Citizen Self Service Portal or at Code Administration, 37 Green Street, Concord NH 03301, (603) 225-8580, [email protected].
If your home is in the State House historic district or the capital core, you likely need a Certificate of Appropriateness (COA) from the Concord Historic District Commission before re-roofing. It reviews material, color, and profile, and in some cases natural slate or copper may be required rather than asphalt. Secure the COA before you order materials.
No. New Hampshire does not license roofers and has no trade exam. Home improvement contractors register (not license) with the Office of Professional Licensure and Certification under RSA 310-A:188–198, carrying a minimum $25,000 general liability policy. Registration is not a competency check, so verify insurance and references yourself.
Concord enforces the International Residential Code, with a 2024 IRC concurrency window running through December 31, 2026. A self-adhering ASTM D1970 ice-and-water barrier is mandatory at the eaves under IRC R905.1.2, and Concord roofs are designed to a 110 MPH wind speed in Exposure Category B.
Concord uses a 70 PSF ground snow load from the US Army Corps ERDC/CRREL TR-02-6 study — the highest in the VHCI New Hampshire set — with an elevation-dependent range of 61.6 to 75.8 PSF. Concord also sees 60.5 to 68.2 inches of annual snowfall, so framing and drainage detailing matter.
Heat escaping the roof deck melts the snowpack, the meltwater refreezes at the cold eave into a dam, and water backs up under the shingles. No shingle sheds water uphill, so New Hampshire mandates an ASTM D1970 ice-and-water barrier at the eaves under IRC R905.1.2. Insulation and ventilation reduce the heat loss that starts the cycle.
Concord sits in a Central New Hampshire nonmetro labor area where the BLS mean roofer wage is $22.65/hour — the lowest of the VHCI New Hampshire metros. Steady institutional work from NH State Government, the State Hospital, and Concord Hospital keeps crews busy without the Boston-driven wage spikes of the border metros.
It can be. The Merrimack River runs through Concord, and properties near it can fall inside FEMA Zone AE. Check your parcel at msc.fema.gov; Zone AE carries a base flood elevation and triggers the 50% Substantial Improvement Rule on major structural work.
